PAPER FILE AND BINDER.

Specification of Letters Patent. Patented A131. 1'7, 191'7.

Application filed September 13,1916. Serial No. 119,894.

ments in paper files and binders and it is an object of the invention to provide a device of this general character comprising two coacting clamping bars together with coacting posts, said bars and posts being-provided with novel and improved means whereby the same may be operatively connected.

The invention consists in the details of construction and in the combination and portant advantages are attained. and the clevice is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a fragmentary View partly in elevation and partly in section illustrating an embodiment of my invention particularly adapted for use as a loose leaf binder;

Fig. 2 is a fragmentary sectional view taken through the device as disclosed in Fig. l with one of the posts in elevation; A

Fig. 3 is a fragmentary view in plan of one of the clamping bars as herein embodied;

Fig. 4 is a View partly in section and partly in elevation of a clamping bar as herein disclosed;

Fig. 5 is a view in endelevation of one of the posts as herein included;

.Fig. 6 is a view in bottom plan ofone of the nuts coacting with the posts;

Fig. 7 is a fragmentary view partly in section and partly in elevation illustrating a further embodiment of my invention and wherein the same is particularly adapted for use as a transfer binder;

Fig. 8 is a longitudinal horizontal sectional view taken through Fig. 7 with the locking plate and the operating screw therefor in plan;

Fig. 9 is a view in top plan of the bar as disclosed in Fig. 7; and

Fig. 10 is a sectional view taken on the line 1010 of Fig. 7 looking in the direction of the arrow and with the locking plate omitted.

As disclosed in Figs. 1 to 6 inclusive, A+A denotes the upper and lower bars of a loose leaf binder constructedin accordance with an embodiment of my invention, each of said bars being tubular and having their opposed faces provided with a longitudinally disposed slot 1 extending the entire length thereofv and through which are adapted'to be disposed the threadedextensions 2 carried by the opposite ends of the posts P.

The ends of the posts P are of sufficient diameter as to bridge the slots 1, and engaged with the extensions 2 are the nuts 3 also of a diameter in excess of the width of the slots land which are adapted to coact with the innersurface of the opposed portions of the bars A. I By this arrangement it will be perceivedthat the posts P may be readily and conveniently adjusted longitudinally of the bars A and effectively maintained in a predetermined adjustment as the requirements of practice may necessi-' tate.' It has also been found of especial advantage to have the opposite faces of the opposed portions of the bars A and at opposite' sides of the slots 1 serrated or otherwise roughened as indicated at 4; in Figs. 3 and at and to have the end. faces of the posts P serrated or otherwise roughened as indicated at 5 in Fig. 5 and with the contacting. face 6 of each of the nuts 8 similarly formed, as indicated in Fig. 6, so that a more effective engagement may be had between the posts P and the bars A.

As is particularly illustrated in Figs. 1 and 2, it is to be noted that the posts P are of a conventional type and each of said posts consists of the telescoping sections 7 and 8 coacting one with another in a well known manner. 7 v

When it is desired to employ my im-' proved device as a transfer binder, the upper bar A has its top portion initially weakened as indicated at 9, so that whenrequired a suitable opening may be produced of the post P which is of a type generally employed in transfer binders. It is also to be understood that the opening 1 in said top bar A is of sufficient width to permit the insertion therethrough of the posts P. As thelower ends of the posts P are adapted to be connected with the lower bar in the same manner as has been set forth relative to the post P, a further description and illustration thereof is believed to be un necessary.

The opposite ends of the upper bar A are closed by the plugs 11 and 12 and the plug l2 is provided with the slot 14 (Fig. 10)

through which is disposed an end portion of the locking plate 15. The opposite end portion of the plate 15 has in swiveled engagement therewith an operating screw 16 threaded through the plug 11 whereby it will be perceived that upon requisite rotation being imparted to the screw 16, the locking plate 15 will be caused to move in one direction to firmly lock the bar A to the post P, or vice versa.

The plate 15 is also initially weakened as indicated at 17 so that when desired suitable openings may be produced for the passage therethrough of the posts P for a purpose which is believed to be clearly apparent to those skilled in the art to which my invention appertains.

From the foregoing description, it is thought to be obvious that a file and binder constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention 1n practlce, except as hereinafter clalmed.

I claim:

1. A binder comprising a tubular bar provided with an elongated slot, a post provided with an extension disposed through said slot, and a clamping member engageable with said extension for securing the post to the bar, the end portion of the post surrounding the extension being serrated and the coacting surface of thebar being also serrated.

A binder comprising a tubular bar provided with an elongated slot, a post provided with an extension disposed through said slot, and a clamping member engageable with said extension for securing the post to the bar, the contacting face of the nut being serrated and the coacting surface of the bar being also serrated.

3. A binder including a tubular bar provided with an elongated slot, a post disposed through said slot and extending through the bar a locking plate within the bar and provided with an. opening through which the post is adapted to pass, means for imparting endwise movement to the plate, and a plug arranged within the bar and provided with a slot through which the plate extends.

4. A binder including a tubular bar provided with an elongated slot a post disposed through said slot and extending through the bar, a locking plate within the bar and provided with an opening through which the post is adapted to pass, a plugpositioned within the bar adjacent an end thereof, a screw threaded through said plug and extending exteriorly of the bar, the inner portion of the screw being in swiveled engagement with the bar, and a second plug arranged within the bar and adjacent the opposite end thereof and provided with a slot through which the plate extends.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
